I have covered every topics till now. I solved full irodov without solutions and other higher problems in Chem and math too. But at time of exam I am not able to remember how i solved it if a similar problem occurs. I mean the knowledge is fresh upto few weeks and then to achieve that level, i have to again read everything and solve those problems again. Many times I also forget the concept even if I know it. Please help me out with it. I guess its the problem of poor memory.
This problem is not uncommon among test takers.
The best way to overcome this is to make notes of problems/concepts which you might feel that you will have to use later in future. And keep revising those notes on a regular basis. It will be of immense help. It seriously works.
